Stabilisation of organic clay using lime-added salt

The main objective of this research is to investigate effectiveness of salts used as an additive in lime-stabilized organic clay. Lime is known to be an effective stabilization method for clayey soil. However for organic clay it becomes less effective due to low increase in strength. Therefore salts...
